Description

react-native --version simply prints nothing. I expected it to print the version of the CLI, as stated in react-native --help.

Reproducible Demo

1. In a RN v0.60.5 project:

node_modules/.bin/react-native --version

The output is only warnings of the type "The following packages use deprecated "rnpm" config that will stop working from next release". No version number.

2. Using npx

npx react-native --version

No output at all!

Seems like a bug. Maybe you'd like to contribute a fix? :)

I'll try!

The issue is due to a naming conflict with built-in commander methods. tj/commander.js#1020

I have submitted a PR now: #713
